PAPER-MAKING- MACHINE.

SPECIFICATION formingpart of Letters Patent No. 694,772, dated March 4, 1902.

Application filed March 1897. Serial No. 626,346. (remotes To all whom it may concern: 7

Be it known that we, JOHN WARREN MOORE and Josnrn A'rwoon WHITE, citizens of the United States, and residents of Philadelphia, Pennsylvania, have invented certain Improvements in Paper-Making Machines, of which the following is a specification.

Our invention relates to certain improvements in paper-making machines known as Fourdrinier machines, in which a wire is traversed over an agitated frame, allowing the pulp to form on the wire in such a manner that the fibers will knit together and form a sheet of paper.

The object of our invention is to provide for the vertical adjustment of the shake-frame, and particularly the frame described in the Letters Patent of the United States granted to us on February 28', 1899, No. 620,548.

In the accompanying drawings, Figure 1 is a side View of; sufficient of. a paper-making machine to illustrate our invention. Fig. 2 is a sectional View showing the flexible-connection between the pedestal and'the shakeframe and the means for adjusting the shakeframe. Fig. 3 is a face view of Fig. 2 on the line 3 3, and Figs. t and 5 are views showing other forms of the means of adjustment.

A is the fixed frame ofa paper-making machine.

B is the shake-frame, in the present instance consisting of upper and lower rails 19 19, secured to the fixed frame Aat one end and coupled to amend frame B at the opposite or free end. The free end of the shake-frame is suspended from standards D by means of flexible plates 61. we also use intermediate suspensiomplatesd in many instances, depending from the standards D, especially in long machines; but it will be understood that the shake-frame can be simply suspended at one end and secured to the fixed frame at the opposite end. a is the making-wire, which passes aroundthe breast-roll b and over the rolls 19 V v The details of construction of the machine are similar in many respects to the machine fully described andillustrated in the Patent No. 620,54S,mentioned above, and as this i n- It has been found by experience that in making certain classes of paper when the machine is run at a certain speed the shakeframe should be in certain positions or angles of inclination to the flow of the pulp to accomplish the best results, and in order toadjust the frame properly We provide the mechanism which we will now proceed to describe.

Adapted to the standard D is a bolt E, having an eccentric section 6 and a stem 6', which passes through the standard and is provided with a nut 6 At its opposite end the bolt has a head a and between this head and the standard is mounted the flexible plate dand a block f. The upper end of the standard is preferably split, as shown in Fig. 2, and ex tending through the standard is a clampingboltf on turning which the bolt E can be 7 clamped tightly in the standard. The eccentrio bolt E can be secured after adjustment to the block f by a set-screwf We have shown the plate at having a lip d passing over the top'of the block; but this is not essential. In some instances the clamping-bolt f or set'screw f or both, may be dispensed with from the construction shown in Figs. 2 and By loosening the bolt E it can be turned so as to raiseror lower the flexible plate cl by means of the eccentric portion of the bolt, a suitable wrench being applied to the irregular head of said bolt, and as this plate is secured to the shake-frame that portion of the shakeframe to which the plate is'secured will be raised'toany extent required. After the cocentric is turned to the proper adjustment the nut e is turned on the bolt, so as to hold the bolt in the set position, and the bolt can be clamped to the standard and to the block f. The said block is engaged by the lips 01 of the plate d and from themtransmitssome of the weight upon said plate to the bolt E, the setscrew f when manipulated so as to clamp the block, with its plate, to said bolt serving efiectually to prevent rotation of the same and maintaining it in any position of adjustment.

The flexible plate at is secured to a bracket 0 on the shake-frame by means of a bolt 0'. In some instances, it desirable, an eccentric bolt, as shown at c", Fig. 2, may be substituted for the bolt 0, so that the adjustment can be made on the shake-frame instead of on the standard, andin some instances, where an extended adjustment is required, both bolts may be eccentric.

In Fig. 4 we have shown another form of adjusting mechanism, used preferably in the mid-position, in which the standard D hasa slot d at its upper end,- through which passes a bolt E having a nut on one end and this bolt E passes through a block F clamped between which and a cap-plate f is the suspension-plate d. The block F has a lugf which extends over the standard, and in this lug is a set-screw g, which rests upon the standard, so that when the bolt E is loosened the set screw 9 can be turned, raising the block F, and with it the flexible plate d and the shakeframe B. This device may be used as a substitute for the one shown in Fig. 2 or may be used in connection with it for the intermediate support of the shake-frame, as this intermediate support can be loosened prior to the adjustment of the end support, so that the end support can be freely raised and lowered and set in the adjusted position, after which the device shown in Fig. 4:, when used in the mid-position, can be adjusted to correspond to the adjustment of the end supports.

It will be understood that while our invenvention is especially adapted for machines using the flexible suspension-plates other suspension means can be used in connection with our invention. It will also be understood that there is one of these suspensionplates at each side of the machine at the free end and preferably one at each side of the 'machine near the middle, and the bolts E of the opposite suspension device may be connected; together by the rod E and operated in unison, if desirable, as shown in Fig. 5, although we have found in practice that in some instances independent adjustment is required, so as to raise or lower one side of the shake-frame more than another, and we profer in building the machine to make each adjusting device independent.

In Fig. 5 we have shown an eccentric bushing e mounted on the eccentric portion 6 and provided with a clampf, so that both sides of the shake-frame can be raised or lowered simultaneously or independently or a double adjustment can be secured.

We claim as our invention-- 1.
